Lean value-stream-map every cross-functional workflow — surface bottlenecks (Theory of Constraints), broken handoffs, WIP overload and rework loops killing throughput.
70% of operational drag lives in cross-functional handoffs, not within functions. Lean VSM + ToC analysis surface where work waits, who owns the queue, and which bottleneck — when fixed — multiplies throughput across the whole system.
A senior-led delivery sequence — not a template dump. Each phase is operated with your team, not handed over as a deck.
Interview function heads to surface the top-10 workflows that span ≥2 functions; weight by volume, revenue impact and complaint frequency.
Value-stream-map each workflow with the operators, instrument cycle-time, WIP and queue-length per stage with real production data.
Theory-of-Constraints analysis to isolate the system bottleneck; handoff-quality scorecard exposing where work waits, restarts or is dropped.
Prioritised improvement backlog ranked by throughput lift; cross-functional SLA framework with explicit owners and escalation.
Rework tracker live with root-cause log, quarterly throughput-review cadence stood up with the COO and function heads.
